Pros

Pro

Great for use when outdoors, going for a run or working out

The BTS Pro is quite robust and can withstand some minor splashes of sweat or rain as these are sweat-proof. They are not completely water-proof though, so you should not get them soaking wet.

Pro

Good sound quality with focus on the lower frequencies

There is good detail in the highs and the mids can also be heard clearly with very little muddiness. The lower frequencies are boosted, resulting in a good level of depth and power to each bass thump.

Pro

Will stay snug on your head

The BTS Pro ear cups sit on the ears with hooks keeping them in place. The flexible connecting band provides good clamping force and can adjust to your head size with continued use. Combined with cushioning on the cups, these are comfortable to wear and will stay in place.

Pro

No long cables to deal with

Bluetooth connectivity allows the BTS Pro to connect with smartphones and compatible music players wirelessly, so cables won't be an issue.

Pro

Companion iOS app adds extra functionality

66 Audio's Motion Control iOS App gives users added functionality, including EQ control and presets selection, battery status indicator, and even headphone position tracking. These features can improve the listening experience and also minimize the chances of you losing these headphones.

Pro

Can last through multiple long listening sessions

With up to 40 hours of playback time at full charge, it's more than enough for most listening sessions. You won't have to charge these frequently.

Pro

Hardshell case makes transport more secure and convenient

A hard shell carrying case is included, which can protect the headphones from minor impact and also make transport much easier. The case also has good aesthetics.

Pro

Can be folded to a more compact size

They are easy to bring on the go as the ear cups can be folded into the headband. This further reduces the already slim and compact size, making them easy to chuck into a bag when on the go.

Pro

Ear cup functions as a remote

The right ear cup of the BTS Pro features buttons for controlling headphone features. You can play/pause tracks, increase/decrease volume as well as answer/end calls by pressing the corresponding buttons, negating the need to pull out your phone to do so.

Pro

Allows taking calls

You do not need to take the BTS Pro off in order to answer incoming calls. There is a built-in microphone which allows you to easily take or make calls in the middle of your run or workout.

Pro

Great combination of features for runners at a reasonable price

The Zeus Outdoor combines Bluetooth connectivity, water resistance and active noise cancelling with a thumpy sound signature. These are fun to listen to, convenient to use and can resist damage due to moisture at a good price.

Pro

No cable hassle as they're wireless

These connect to a sound source via Bluetooth, so only a very short cable connects the two earpieces. This can help improve your mobility and minimize cable-related distractions.

Pro

Active noise cancelling minimizes ambient noise

Ambient sound leaking in to your music can be drastically reduced by the active noise cancelling feature. You can better focus on your music, as well as your run/work out.

Pro

Won't easily get damaged by liquids

These have an IPX7 rating which makes them water resistant so they can be used while running, even when it's raining. Do take note that submerging these headphones beyond a certain depth will negate their water resistance.

Pro

Powerful bass

Bass hits are powerful and forward, which should complement the upbeat and thumping music that most people listen to when working out. Highs and mids are recessed though, so these are best for bass lovers.

Pro

Snug and secure fit

Ear hooks are attached to the earpieces which provide extra grip over your ears, so these will not fall off easily. The short connecting cable also minimizes the weight that may pull down on the earpieces .

Pro

Comes with a good assortment of accessories

You get a number of silicone ear tips in different sizes, some foam ear tips as well as a carrying case.

Pro

Good battery life

These can last up to 8 hours of continuous music playback.

Cons

Con

Some distortion can be heard at lower volumes

There may be audible levels of a scratching sound or distortion when using these at lower volume levels. This can be quite distracting, and can have a negative impact on your listening experience.

Con

Motion Control App is for iOS only

At the moment, users of non-iOS devices will not be able to take advantage of the companion app's functionality. However, 66 Audio have announced that an Android app is currently in development.

Con

May sound quite muffled for some

The highs are quite recessed to give way to the powerful bass. This results in a sound that has a muffled feel which not everybody may like.
